WRIST DRIVING SIGNAL LAMP Filed Feb. 8. 192s ATTORNEY. f

Patenteel Dec. 24, 1929 UNETE" JOHN E. NASH, OF BELLINGHAM, WASHINGTON WRIST DRIVING SIGNAL LAMP Application filed February My invention relates to improvements in wrist driving signal lamps, and an object thereof is to provide a controllable flash signal lamp adapted to be carried on a wrist of the driver.

Another object of my improvement is to provide a wrist flash lamp operable by a natural hand movement on the wrist.

And a further object of my improvement is to provide a wrist lantern adapted to contain dry battery cells to provide current for the lamp therein.

Other objects of my improvement will appear as the description proceeds.

I attain these and other objects of my improvement with the mechanism illustrated in the accompanying sheet of drawings, which forms a part of this specification, and in which Figure 1 is a top plan view of my wrist signal lantern, Fig. 2 is an elevation view of the front or cover end of the lantern, Fig. 3 is a side elevation of my wrist signal lantern fastened on top of the wrist of the left hand, Fig. 4 is a rear end elevation-of the lantern, and Fig. 5 is a vertical section of Fig. 1, on the line 5-5.

Similar characters refer to similar parts in the several views. Certain parts are broken away for lack of space or to show other parts hidden thereby.

With more particular reference to the designated parts: The main body of the lantern 6 is preferably a flat box of meta with semi-cylindrical edges and flat bottom fastened thereto. A cover '7 has flange (7 to overlie the open end of the lantern body and is hinged to said body at 8. The edge of the body opposite said hinge is turned outward at 9, Fig. 8, to provide a catch for the rolled edge 10 of the cover with which it is engaged. The construction here provides for a limited vibration of cover 7 on hinge 8 without disengagement from catch 9; To open the lantern and swing the cover more fully on said hinge the lantern body is pressed inward near the catch, releasing rolled edge 10 from engagement therewith. To restore engagement between cover and body said pressure is again resorted to and a reengagemellt of 10 and 9 is easily effected.

Two clips 11 are fastened longitudinally of I the body on one side near its edges to engage strap 12 therewith. These clips are most clearly shown in section in Fig. 5 from which the strap is omitted.

Strap 12 is preferably passed through both clips and is provided with a buckle or other device for securely fastening the strap in a loop to snugly embrace the wrist A and retain the lantern on the back thereof in a secure manner.

The human hand and wrist shown in outline at A has lantern 6 mounted thereon in Fig. 3 in a way to cause rolled lid edge 10 to bear on the back of the hand near its union with the wrist so that when the hand is swung outward on the wrist joint to its position shown in dotted lines at A the back of said hand will force lid 7 to swing on hinge 8 in the direction of the arrow shown in Fig. 3 1iointil it is entirely seated on top of the lantern ody.

An opening is made in the hinge side of the lantern body near said hinge, preferably, and the edges thereof are shaped to retain a lens 14 as shown at 13. Lens 14 is preferably red glass.

Two small dry battery cells are placed in the lantern in block 21 which is shaped to fit said lanterns interior and receive said cells 15 and 16 to maintain the same apart and free from contact with the walls of the lantern. Block 21 is preferably of wood or similar light insulating material. Cells 15, 16 are preferably placed relatively side by side with reversed ends juxtaposed; The central terminal. of cell 15 is designated as a, and the central terminal of cell 16 is designated as (4 Elliptical spring 17 is centrally fastened to lid or cover 7 with one end adapted to bear on electrode a and its other end proximate I to the bottom end of cell 16, when cover 7 is in its illustrated position, and bearing on said bottom end to make electrical contact there with when cover 7 is fully closed as above explained. Spring 17 is fastened to the cover by rivet 18 and electrically insulated therefrom. Spring 17 is shaped to bear on electrode a}? and react between the same and the i does not glow.

cover to cause said cover to move outward till stopped by rolled edge 10 bearing on catch 9. Then when said cover is fully closed, as by pressure from hand A against said rolled edge in the direction of the arrow in Fig. 3, end a of said spring is caused to bear on the outer electrode of cell 16 and spring 17 serves to connect said cells in series relation.

7 A recess is made in block 21 beneath lens 14 and lamp socket 22 is set therein centrally beneath said lens. In said socket is screwed incandescent electric lamp 24 the central tere minal of which contacts with connection a one end of which is centrally placed beneath said lamp.

Connection (r is extended through ahole in block 21 and its other end terminates in spring 19 adapted to make electrical contact with the outer electrode of cell 15 as shown in Figs. 1 and 4.

Que end of connection 23 is connected with socket 22 and is extended through an opening in block 21 and terminates below the same in spring a which makes electrical contact with the lantern case when block 21 is in place in said lantern, as shown in Fig. 5. One end of spring 20 is fastened to said lantern case and the other end bears on the inner electrode of cell 16 to make electrical contact therewith as shown in Fig. 1. Thus springs a and 20 join with the lantern case 7 to complete the series connections of the two cells 15 and 16. So that when spring end a contact-s with the case of cell 16 current from said cells 15 and 16 pass through lamp 24 in series. And when wrist and hand A are in their fullline positions lantern cover 7 is retained in its illustrated position with spring end a out of contact with electrode 16 and lamp 24 lVhile, when said hand is turned to its dotted-line position at A cover 7 is fully closed causing spring end-a to close the circuit with the outer electrode of .cell 16 and lamp 24 is caused to glow and a red light emanates from lens 14.

By equipping the hand used to give the traffic signals with my wrist flash light said signals are even more conspicuous in the dark than when given by the hand alone in the light, which is the main objective of my invention.

Having thus disclosed my invention, what .I claim as new therein and desire to secure adjacent the hand on said wrist.
